Custom because it'll benefit from a +1 SpA / SpD and maybe Atk from Girafarig. It's walled by Altaria, but I use it with Samurott and Probopass.

I used Murkrow before, and it was an extremely strange set. I made a crappy team just to test it (and I was tired of BP chains) and that was a nice Murkrow set. If you take Cinccino out, this set makes the day.
